What we're doing
The Waipaoa River Flood Control Scheme (the scheme) was designed in 1949 and was completed in 1969. It was valued by Council in 2009 at $35.7 million which excluded the 638 hectares of land owned by Council as part of the scheme.
The scheme is considered to be one of Council’s most valuable assets. It protects some 10,000 hectares of fertile floodplain land and has increased the amount of land being used for high yield horticultural purposes.
The scheme includes 64km of stopbank and associated pipes located approximately between Te Karaka township and the Waipaoa river mouth.
About the project
The project is designed to improve capacity of the existing flood control scheme and:
♦ increase the top width of the existing stopbanks from 1.5m to 4m and raise the height between 1-2 metres in some places
♦ maintain flood protection for a one-in-100-year flood event (or a 1% chance of that sized storm occurring in any one year)
♦ account for the effects of climate change out to 2090 (2.1 degrees warming climate and 0.67m seal level rise)
♦ address river bank erosion
